A Study on Flame Structure of SNG Fuel Part I : Interaction between Flames Downstream

SNG 연료의 화염구조에 관한 연구 Part I : 화염후류간 상호작용

A combined experimental and numerical study has been conducted to investigate the downstream interaction between simulated SNG-air premixed flames in fuel composition of 91% $CH_4$ + 6% $C_3H_8$ + 3% $H_2$. In this study, the effects of fuel molar concentration(lean-rich) and strain rate($a_g$) were major parameters. A main focus is to investigate flames behavior and chemical interaction at flames downstream. The numerical results were calculated by OPPDIF application. The reaction mechanism adopted was USC-II model including C3 reaction.
